I run my flowering room at 73°, with a 56 to 57% humidity. Vegetation stage is just growing the burgers. Flowering stage is where everything pops!!While your plant may not show signs of heat stress it still may benefit from lower temperatures - higher temperatures can lead to loss of terpenes, slower growth, and increased susceptibility to pests... Just because your not having problems does not mean that your results would not improve if you made some changes.... it's also notable to mention that veg phase can tolerate higher temps, it's during the flower phase that you will more likely see the difference in performance...
I'm having no problem in vegetation I've been growing for 3 months. no probs. I have to keep them in bed that long because my flowering room is packed!!Spoiler alert.... air temps are not nearly as important as leaf and plant temps. Some LED grows can have a 10f difference between air temps and leaf temp.
Many factors contribute to this and while air temp is one of them imo it's not accurate to judge what's ok for the plant and what's not.
I just researched ask,crazy questions. Most of it is from trial and error. I've read a lot online by the forums. Lot of contradictions.interesting - I think I read another of your posts about this - could you point me to more info or provide some more details on ideal leaf temperatures ? I guess i need an infrared thermometer...
Half the time this phone can't understand this country boyI just researched ask,crazy questions. Most of it is from trial and error. I've read a lot online by the forums. Lot of contradictions.I read a lot of people between 70 and 80° is the ideal temperature. Now if I see my Lee's wrinkling or look like they're stressed by the heat I raise my lights. They're going to grow no matter where your lights are in vegetation. I've been gone for about 5 years I've lost crops I've screwed up!!! But I'm there now
Ideal leaf without co2 are 75-77f but 70-80f usually has no issue... very quickly above 80f you will start to see stress.
I have a VPD thread that touches on some of it.
VPD (vapor pressure deficit)
Ok i was gonna sit down and write out a whole article but i have been lazy so instead instead I'm going to copy paste because im lazy. This is not my work so let start. You may find this very long but its worth the read. Some may want to skip ahead. I have added here and there to what i feel is...www.thcfarmer.com
Send me some details of information on what you're telling me. If you wouldRemember room temp and leaf temp are very different some can run high 80s and see no heat stress and good leaf temps
I like to readSend me some details of information on what you're telling me. If you would
That's a long read I understand temperature CO2 air flow water evaporation take it in water with the leaves. Now these articles are high dollar outfits with ideal conditions. Now as we all on this forum or home growers. Most the people on here can't afford all what you're saying to put in their rooms. It took me 2 years to get my room set up. Now if I was rich and a chemist. I wouldn't have to go in them rooms everyday. I was raised on the farm been working on one since I was 12 years old. Things we use to make plants grow you would not believe.Photosynthetic response of Cannabis sativa L. to variations in photosynthetic photon flux densities, temperature and CO2 conditions

I'm not saying they should do anything.... just sharing information based on facts not broscience. I was simply stating that leaf and air temps are not the same and when you asked for me to provide reading to back up my claims I provided it.That's a long read I understand temperature CO2 air flow water evaporation take it in water with the leaves.
